Abstract:
DC Boundary stone locations. The dataset contains locations and attributes of DC Boundary stones, created as part of the DC Geographic Information System (DC GIS) for the D.C. Office of the Chief Technology Officer (OCTO) and participating D.C. government agencies.
A database provided by A. Morton Thomas & Associates, Inc. identified DC Boundary stone locations. DC Boundary stones field surveyed by GPS and conventional survey methods. Surveyed accuracy is +/- 5cm horizontal and +/- 9cm vertical.
All DC GIS data is stored and exported in Maryland State Plane coordinates NAD 83 meters.
METADATA CONTENT IS IN PROCESS OF VALIDATION AND SUBJECT TO CHANGE.
Purpose:
This data is used for the planning and management of Washington, D.C. by local government agencies.
Supplemental_Information:
STONES North, NE1, NE8, East, SE1, SE9, SW5, West, NW1, NW2, NW4, NW5, NW9 = Field Survey Method: Conventional - 2 survey control points were set at the site utilizing GPS-RTK. Conventional survey total station was then utilized to data collect angle and distance measurements to the stone. The Stone was located at the top center point for both upright and leaning conditions. 3 color digital photos were obtained for the stone. A measure down was obtained from the top of stone to the ground.
STONES NE2, NE3, NE4, NE5, NE6, NE7, NE9, SE2, SE3, SE5, SE6, SE7, SE8, SW1, SW2, SW3, SW4, SW6, SW7, SW8, SW9, NW3, NW7, NW 8 = Field Survey Method: GPS-RTK A minimum of 3 consecutive GPS-RTK observations were made with each observation being a minimum of 30 seconds in length with data collected at 1 second intervals. The observations were averaged to produce the resulting coordinates and data was reviewed to confirm project accuracies were met. The Stone was located at the top center point for both upright and leaning conditions. 3 color digital photos were obtained for the stone. A measure down was obtained from the top of stone to the ground.
STONE SE4 = No survey worked performed. Stone is located in private residence waiting to be reset by joint survey society effort. No plans at this time for resetting
STONE South = Could not survey due to site being under construction with stone wrapped in burlap and packed in sand. Approximate coordinates (+/- 0.4') obtained from AMT surveyor working for PCC at Woodrow Wilson Bridge
